MigrationPhase
imported is an adopted array waiting for its point of no return: the data disks are mounted read-only and parity and cache are untouched (startMigrationImport). The verify phase (startMigrationVerify) moves it to verifying while it runs, to verify_failed when it found a mismatch or did not finish, and to verified when every comparison passed; only verified leads to the point of no return (initializeMigrationParity). initializing is a point of no return that stopped after the former parity and cache disks were formatted and recorded: running it again finishes it and erases nothing.
